Question: A butcher stands 5 feet tall. What does he weigh?
(Move your mouse over the prize for the answer.)

This two-piece slide card is one of 32 in a series from the 1970's. It consists of a 1 3/4" by 1 1/4" outer sleeve with cutouts on the front and back, and a question and answer card that fits inside it. When the Q-and-A card is inserted, one of five questions relating to numbers is exposed on the front, and the answer to that question is revealed on the back. Sliding the card along displays another question and its corresponding answer.

Other slide cards in this ID 1395 series (each with 5 questions and answers) include these titles: Alphabet, Animals (6), Birds (3), Cities, Dinosaur, Elephant, Fish, The Heavens, Historical, Insects (2), Measuring, Ocean, President, Riddle, Solar System, Space, Sports, State, Tail, Tree, U.S. Facts, Weather, and Where We Live.

There is some variation to be found among the cards, as shown below. In addition to the slight color variation of the two Cities slide cards, the presentation of the instructions and identification is different on the back. With the one on the left, they are printed in black on a white background block; with the one on the right, they are printed in yellow without the white background. Also, the one on the right is slightly wider.
